Not long ago, late Dr. Stephen William Hawking said that the Earth could become a big flaming planet by the year 2600 because the world’s population will keep increasing while the resources on the Earth will keep decreasing to a point that it can no longer afford the people. Before 2600, people will have to create a fast spaceship to find a habitable planet.

With this news, we should think about what we have to do next. We have cut down too many trees and built too many skyscrapers. We have also killed lots of animals so that they are beginning to become extinct. At present, the Earth is becoming warmer, and the melting icebergs have caused a rise in sea level.

What can we do to protect the Earth? The following is some advice for us to help protect our planet.

Firstly, we have to stop cutting down trees. Secondly, we can reuse paper, which is a good idea to make full use of paper. Thirdly, we shouldn’t waste water or natural resources. Last but not least, we should protect animals and stop killing them. What’s more, we should make friends with animals.

Now Hawking, who made brilliant contributions to our world, has passed away and I am in deep sorrow. Let’s do our best to protect the Earth, or it will be destroyed.
